ok guys i got my LQ9 and i wanted to use an LS1 intake and all that stuff but then i got my bracket and i noticed the whole wasn't there for the alternator.

(barrowed this picture from another site.)
So i said well the spot is there why not make the whole. I was scared to death to do it but if i wanted to use the ls1 intake and all that good stuff so here are the tools you will need
a drill
i used 3 bits one small for the pilot hole one a little bit bigger and then an 11/32 bit
a 10x1.50 plug tap


So what i did was bolted the bracket on with the bottom bolt
and lined it up



I took a very pointy pencil and lined it up in the center


once i marked it i measured how much i needed to drill


and once i did that i used some tape to mark the bits so i knew how much i needed to drill


i didnt picture this but i drilled with a smaller bit first then a medium size bit then the 11/32 bit needed to tap the whole


once i got that done i tapped the whole with the 10x 1.5 tap


and then ended cleaned it with an air compressor and cleared out the and made sure nothing was left in there. here is what i ended up with



hope this will help everyone later on!

 

very nice write up! looks good!

 

thanks i was scared to do it but it turned out good

 

Looks good, ill be doing this on my 4.8 but I'm adding 3/4 spacers so I can run my truck acc.

 

it was easy man! hope it works out good for you

 

Looks good, I will be doing this tonight. I just purchased a "R" drill bit for that hole.

 

Nice write up!
I did the same modification about a year ago.
Thanks for sharing.

thanks man! again its one of those things i hope it helps others because i couldnt find anything when i was doing it

 

Someone should sticky this, seems like a very well done writeup and it could save some search time. Just my 2 cents.

 

thank you that makes me feel good

 

Good stuff..I think a bunch of us have done it the same way..lol...

Definately easier if you have a level..

 

You know whats way easier is running the alt on the pass side. Top mount area.
Like the bracket i use on my cars. Plus i hate going down there to swap alternators and sometimes, the stock location hinders many turbo tubing routing options.

 

MASTER MECHANIC BRAND!!!!!!!!!!!!!!

thank you for shopping at True Value Hardware(my family has owned/run a truevalue since i was only a few years old)

 

I made my own bracket for that on my S10..




But in my Monte Carlo SS I run the F-body Accessories with room to spare..

 

great ideas and cool thread. Thanks.

 

i dont have may other places to go to around me and true value is a half mile from my house

 

thanks i am glad you liked it!
